Excellent product.

It fits well. I can tell that I sleep better after wearing the ballcap for most of the day. I do think it is a well made cap and the fabric is attractive and durable,

Not for smaller heads

I would have given this 5 stars however since the cap is not made for smaller heads, I am giving it 3 stars. To make it fit snug I have to adjust the velcro strip to its limits and it causes it to hang out the back and it looks goofy. The material is good though and the shipping is prompt.

Great style and comfort

I’ve had this cap for a couple of months now and I must say that it looks and feels great. It fit perfectly straight out of the box. I’m happy with the black color, but I can understand why some would like to see this cap offered in other colors. You can’t really wash this cap as you can other baseball caps due to the material, so you have to take very good care of it.

I like the cap. But hope in the future you can make other colors. Black cap isn’t great summer color. Please consider pink .

Good, a little wide for me but ok. Good material.

EMF Radiation Protection Baseball Cap

Happy to receive my cap and have been wearing it when I go for walks everyday - along with my defendershield little over the shoulder bag where I keep my phone. The only issue I have with the cap is that I have the velcro adjustment strapped pulled across to its limits (small head?), and this then causes the cap to “bubble” in various areas across the top of my head-which isn’t the look I was going for if you know what I mean. Overall I am glad to look like a bubble headed fool for the protection - but it would be great if you could make the cap in 3 sizes - with measurements - because lets face it - one size doesn’t fit all .

Absolutely love the concept

I love the hat.. I definitely can see it being problematic if you have a big head and it not fitting. Mine fits but is snug. I do wish you could adjust it more. Only qualm is i wish they made the rf mesh extend out to the bill cap instead of it just civering the top of head for more extensive protection. On that note, I have bought quite a few items from Defendershield because of the quality.... I came from an RF safe sleeve over to defendershield phone sleeve and havent looked back since. Defendershields an industry standard known amongst anti EMF/Radiation Frequency crowd. You really cant go with their products. You know the saying.. You get what you pay for.. abd its no different with Defendershields products. I also own the Winter Beanie which I perfer to wear in winter over the hat cause it covers more area on my head. Still a great product if you happen to drive around or be by 5g towers etc

EMF Base Ball Cap

I gave my first cap to my granddaughter and then I purchased a new one for myself recently. I think this one actually fits better and I am wearing it most of the time. I make a point of wearing it in my car as well as outside. It is a must have item for all of us!

Should’ve read the fine print, I suppose

Wayyy too small. I can definitely feel the emf protection, I’m rather sensitive. But it’s uncomfortably small for me.
Measure your head before purchase (and take into account if you have a lot of hair on your head).
Because I technically wore it, there’s a 10% restocking fee, then I’d have to pay for shipping, and find the time to go to the shipping place.
No thanks!
This will now be used as a emf-proof pouch to put small electronic devices at night.

Hello,

Thank you for contacting DefenderShield. We apologize for the experience you've had with the baseball cap. We have passed this information on to our product development to improve future products. Should you choose to return the baseball cap the restocking fee will not charged as long as the cap in good condition.

ATTRACTIVE BASEBALL CAP

This is only the second such style of cap that has fit me this well. I cannot yet tell if it is protecting me from EMFs but I am trusting it is!

Too Small and Not Adjustable

I received this as a gift. I am a 5'5" woman with an average size head. The hat is too small and as I wear it, moves up my head and pops off. It tends to give me a headache. For the price, not worth the money if I can't keep it on my head and is not comfortable. The fabric quality seems excellent and sewn well. It looks good on. Would be a great hat if they work out the sizing. Going to see if I can exchange it for the beanie.

Not sure

Really hard to say about its protection. I do look like the uni-bomber, so I have gained some privacy. It’s a personal choice and is worth a try to someone struggling with EMF

J
Justin Roberts
Too small

It looks great and looks like high quality material. But it is too small for my head. If I put it on it is skin tight. I am not sure what to do with it. If it fit me well I would give it an excellent rating.

Hello Justin,

Thank you for contacting us. We apologize that you're not satisfied with your baseball cap and kindly ask that you initiate a return using the link on our website. We will promptly initiate the refund process upon receipt of the product. https://www.defendershield.com/returns

Great customer service

Great customer service.

Defender Sheild is working on a larger size of the. Although it is sleek and protective. It's too small for me. They worked with me on a return for this reason

Works well

I know this cap works because the GPS on my Garmin watch didn’t work for most of my run yesterday. That was unfortunate for my run but I at least know this hat really does block frequencies.

Good quality

I found the cap to be helpful and well made. I tried the Wormore hat as well, but the Defendershield is much better quality. The lining goes all the way around inside the cap and the material is more form fitting. I just wish I had bought this cap earlier.

Good Purchase

The cap is comfortable and not too big. I'm a petite woman and it looks like a regular baseball cap. I'm grateful to have a summer option for protective headwear.

Great Cap

I love this cap! It looks like a regular cap from the store, so no one would know its EMF. I think the quality is great and love the fabric. I have a small head so it probably would be even better with someone with a bigger head, however, I think it still looks good on me. Highly recommend.

I bought for my son to use while he’s gaming. So far he is able to wear it with his headphones over it without an issue
